#199 of 208 43 days and 14,377 km (9,155 miles) by conwelpic Sep 22, 2009 (2:22 pm)
I have recently returned from a 14,733 km (9,155 mile) trip across the northern states and back across Canada to our place in Ontario. We traveled over a lot of varying terrain from steep grades to 75 mph interstates, from sea level to eleven thousand feet. I generally filled the tank up between the 500 - 600 km mark (and sometimes well over 600), so they are not short runs and therefore a lot of variety of driving in that time period. Also experience temperatures over 100 F, so a lot of times the a/c was on almost all the time (it worked great).   My overall average for the whole trip was 35.3 mpg to the Canadian gallon or 29.4 mpg US. The lowest mileage I got was 31.6 mpg CDn (26.3 mpg US) and the best was 40.4 mpg CDN (33.5 mpg US).   Overall very pleased with the mpg and the car was flawless throughout the whole trip.   Canadian EX, 2008, 2.4L
#200 of 208 09 Rondo I4 - first 10 tanks by 9394 Sep 23, 2009 (9:07 am)
09 Rondo EX I4 purchased on August 2, Vancouver, BC   1st tank: 19mpg (12.5L/100KM) - 100% City   Return trip to Oregon coast: 2nd tank: 30mpg (7.9Lpk) - 100% Hwy 3rd tank: 25mpg (9.4Lpk) - 100% Hwy.....why so bad compare to 2nd tank 4th tank: 31mpg (7.5Lpk) - 100% Hwy   i noticed that the FE varies from tank to tank even though in similar weather and driving condtions, i wonder i may NOT be filling the tank 100%, possibly due to the tilting degree of the platform at the pump? anyone else has that problem?   after that i made a return trip to Calgary, Alberta and averaged: 5-8th tanks: 29.5mpg (8Lpk) through the mountains.   9-10th tanks: 19mpg (12.5Lpk) - 100% City   now at 3000 miles (5000km), hope FE will improve, especially for the City, because i'm not too impressed with 19mpg, my much bigger minivan is getting 17.5mpg.

#201 of 208 FE by telesave Sep 23, 2009 (9:24 am)
I've been happy with the rondo, but always unhappy with the FE too! i also only get a little bit better FE than my much larger sienna minivan.   (i have a 2007 rondo with 40k)
#202 of 208 Variability in mpg by garnermike Sep 23, 2009 (11:32 am)
Replying to: 9394 (Sep 23, 2009 9:07 am) I have a 2 year old LX I4 with 21K miles. Your fuel mileage is very close to what I was getting until I passed the 15K miles odometer mark. At about that mark, my 100% city mpg improved to 21 mpg, and my 100% hwy mpg improved to 29 mpg. My mixed driving is now consistently 24-26 mpg.   But that 24-26 mpg calculation is an average based across several tanksfuls. I have since Day One gotten wide swings in individual tankful mpg computations. 17 mpg on some tankfuls; well over 30 mpg on others. I am convinced that the car never gets that bad -- or that good -- mpg. I have no idea why the car will sometimes take on more fuel or less fuel when filling up, such that I might go 50 miles before the fule gauge needle budges, or just 15 miles before it budges.   I described this all to a Kia technician. He said that it's probably a bad fuel tank level relay gismo. I nevered bothered to have it fixed, because I believe that, over a number of tankfuls, I'm getting an accurate estimate of my mpg.

Replying to: garnermike (Sep 23, 2009 11:32 am) exactly, the distance it takes for the fuel gauge to start dropping varies a lot, even under the same driving condition.   i will try to fillup at the same gas station, same pump to see if this problem will go away.

Replying to: 9394 (Sep 23, 2009 9:07 am) Don't complain about 19 in town.My 4 cyl Optima gets less than 15 city.

Replying to: 9394 (Sep 23, 2009 9:07 am) Be impressed my friend.My 4 cyl Optima barely gets 15 MPG in the city,Another story on the highway,consistently over 30 and a high of 40.7.

Replying to: 9394 (Sep 23, 2009 9:07 am) My wife's now gets 25MPG everyday driving, which is about what it was getting on straight interstate when it was newer. I think she was over 15K when it started to get better as well.   Sad that it only 1.5MPG better than other vehicle. I too traded from an Aurora V-8 to a Malibu I-4 AT6. Not yet happy with the MPG difference when the overall quality of ride is considered. I'd be much happier if gas was still $4.50/gallon. You might look at it from that view, ie, driving the same distance with both vehicles, assuming same size tank, you would currently be saving about 1 gallon per fill. That would now be only $2.50, but at old price $4.50, and if gas goes to that $6 that Dems were talking as a mark (adding tax to discourage consumption) we both will be happier with our vehicles.

Replying to: e_net_rider (Nov 05, 2009 12:59 pm) It's both curious and also validating that many Rondo owners have had similar experiences to my own. At 26, 000, my Rondo ('07 LX I-4) has settled into its "calling," with mpg consistently ranging between 21 and 31 mpg, averaging right around 26. It got better after 15,000 miles, and still does a lot of inexplainable swinging between the 21 and 31 marks. I don't see the odd 15 mpg or the odd 40 mpg.

Replying to: garnermike (Nov 05, 2009 7:01 pm) i have been going to the same gas station, same pump for the last few fillups, the FE swinging problem no longer exists.   also, i don't top up anymore, i estimate how much gas i can pump and slow down the pump at the last 10 percent and stop pumping at the first click.   .
